    Why the Fall of the 'Caliphate' in Syria Will Not Ease Western Security Concerns

    A Syria and Iraq free of ISIS do not, unfortunately, free the West from the ISIS threat. Instead, ISIS is likely to either disperse, with its followers prepared to carry out a range of further attacks, or attempt to regroup in the fragile states of Africa.

    ISIS's oil revenues declined from a peak of $40 million per month in 2015 to $4 million per month as of early October 2017.
